TURKEY (MSS M1-90-S | MSS M55-S) 2016-ON GOING

Location
Kayas – Kirikale Arasi, Turkey
Year
2016-...
Project
Type: Four high-speed railway viaducts (V7, V9, V10 and V15), total length of 6151 m (20180 ft.) (M1-90-S = 4454 m (14612 ft.) | M55-S = 1697 m (5567 ft.)
Typical Span: M1-90-S = 90 m (295 ft) | M55-S = 45 m (147 ft.)
Deck width: 12,7 m (41 ft.)
Typical Cross Section: Box
Equipment features
Model: MSS M1-90-S | MSS M55-S
Construction Type: In Place
Type: Overhead
OPS System: Integrated
Performance: M1-90-S = 14-day cycles | M55-S = 9-day cycles
Challenges
Construction of 90 m (295 ft.) spans with movable scaffolding system, the largest of our days
Elevated height of pillars, assembly of supports at elevated heights due to the height of the pillars
Respecting the basic design spans
Major reduction in the cost of viaduct construction
Solutions
Wholly autonomous equipment lifting the supports by means of own overhead cranes
In order to obtain the optimisation and reduction in construction time, two items of equipment are used
Use of safe, industrialised method
Results
Work in progress
